Item Description

A showy and uncommon three-sided rib from this noted Zacatecas mine. Many, cute, small arborescent clusters and clumps of copper crystals are coated by malalchite with nearby uncoated copper crystals on the front, top and back. Very glassy, colorless calcite scalenohedrons richly cover all three sides, with the matrix on the bottom. Choice and uncommon combination material from the Bob Trimingham Collection. Orange fluorescence.
